Concept:The French policy that treated colonised West Africans as collaborators or associates, not as French citizens.
Explanation:The Assimilation policy aimed to make Africans French in culture, language, and law.
It did not create a partnership because it absorbed territories into France.
The Association policy replaced it and recognised the separate culture and rulers of African societies.
Under Association, local chiefs and authorities were allowed to cooperate with France in administration.
This arrangement therefore made the colonised French West Africans partners with France in her colonial project.
Answer:B. Association policy.
